Had one when I was in school abt 8 yrs ago. Mine was Carburetted 4 spd, the new ones are EFI 5 Speed
i) My car returned an Avg - 10 kmpl (Sales broucheures claimed test results of abt 16 kmpl)
ii) Used my car for 2 yrs, Never broke down on me.
iii) Trust me, U'll Have to stand on the gas pedal to hit 60 kph with the A/C on and 4 adults in it.
iv) 2nd hand value is not that great. Unlike Japanese vehicles, Marutis Depreciate in LK.. ( I bought mine in India. Out there a new vehicle depreciates by 15-20% the first yr )
v) The body is fine, not really prone to corrosion. You can get a preventive underbody treatment done.
Hope this helps
Cheers!
